linrrnn STATES PATENT @errent ALVIN W. VAN DORSTON, OF SOUTH BEND,INDIANA.

CAR=BUNIPER.

SPECIFICATION forming part of Letters Patent No. $78,532, dated February28. 1889.

Application tiled June 30, 1887. Serial No. 242,980.

To all whom it may concern:

Be it known that I, ALVIN W.VAN DoRsToN, a citizen of the United States,residing at South Bend, in the county of St. Joseph and State ofIndiana, have invented certain new and useful Improvements inFreight'Car Buffer-Blocks; and I do declare the following to be aclear,vfull, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawing, and to lettersand figures of reference marked thereon,whieh forma part of thisspecication.

My present invention relates to improvements in freight-car buffers,wherein said buffers are secured to the front car-sills.

The object of my improved buffer is to provide a compact and elastic oryielding buffer by means of a piston operating against indiarubberrings. Y

In the accompanying drawing, the figure is a top plan View of the frontcar-sills provided with my improved buffers as they appear seber rino',ai and in the outer end of said iston is located the india-rubber ringsor cushion a. In this construction the piston e has (No model.)

buffer a* is located on the opposite sides, placed as rights and lefts.In this manner the cushioned buffer always comes in contact with therigid one. By this means the rigid shocks to which cars are subject withthe blocks termed deadwoods maybe dispensed with, and damage to cars,stock, or freight of any kind will be greatly diminished.

In the construction of my improved buffer it will be seen Vthat theframes a? and rigid buffers are secured to the sill by means of thebolts (dal, and that the piston is secured in u the frame ai by meansofthe bolt a5, which allows the piston to move back and forth whencoming in contact with each other, thus protecting the cars, thecouplers, and draw-gears.

Having fully described my invention, what I claim as new and useful, anddesire to secure by Letters Patent of the United States, is

l. In a freight-car buffer, the combination of the frame a2, the pistone, and head a, with the bolt a5, substantially as shown, and 'for thepurpose set forth. K

2. In a freight-car buffer, the combination of the frame a2, the pistone, and head c, with the india-rubber cushions a and a", substan tiallyas and for the purpose set forth.

3. In a car-buft`er, the head a and piston e, having india-rubbercushion a, in combination with the frame a2, and cushion a3, forming areciprocating buer to the rigid block at, substantially as described,and for the purpose set forth.
